Weather MCP Server

Overview

This project implements a Model Context Protocol (MCP) server that allows AI assistants (such as Claude) to interact with the National Weather Service (NWS) API. The server provides real-time weather alerts and forecasts for a given location.

Features

• Retrieve active weather alerts for a given US state.
• Fetch weather forecasts for a specified latitude and longitude.
• Implements the FastMCP framework to expose tools for AI interaction.

Technologies Used

• Python
• FastMCP
• httpx (for asynchronous HTTP requests)
